Abstract
A method and system for detecting the transmission of preidentified content, such as copyrighted material, over an Internet Service Provider (ISP) network. A set of rules is provided to identify one or more traffic flow profiles of data streams transmitting preidentified content. Preferably the rules are adaptively created through analysis of actual ISP data in conjunction with data suggesting an initial set of profile characteristics. The rules are applied to data streams being transmitted in the ISP network, so that data streams fitting one or more of the profiles are identified. A database contains, e.g., as digital signatures or fingerprints, one or more items of content whose transmission is sought to be detected. Data streams identified as matching a profile are analyzed to determine if their content matches an item of content in the database, and if so, an action is taken which may include interrupting the transmission, suspending an ISP account, or reporting the transmission. An ISP with a system performing this method may offer services to content providers, and a plurality of ISPs may jointly use a single database of preidentified content to be compared to each ISP's iden…
